A A BY ATTORNEY v:

letteredv Aug. 21, 1935 UNITED STATES 1 Claim. (Cl. 141-7) Thisinvention relates to a device for sterilizing vcanning jars, bottles,and other analogous vessels'or receptacles.

The device is designed and adaptedto utilize 5 steam or other vaporousmedium for sterilizing the various articles mentioned, and may be usedadvantageously as a household device'for the stated purpose. g An objectof the invention is the provision of a device of the indicated characterwhich facili'- tates the cleaning or 'sterilizing of articles such' asthosermentioned.`

A further object of the invention is theprovision of a simple andinexpensivevaccessory which may be used in conjunction with an ordinaryhousehold article, such as a pan or other similar rvessel adapted tocontain water togbe converted into steam, so that the steam may be usedto sterilizek or clean rvarious' articles when subjected thereto.

The nature of the invention andits distinguishing features andadvantages will. appear when the following specification is read inconnection with the accompanying drawing, in which Figure l is a centralvertical section of a device embodying theV features of theinvention inuse;

Figure 2 is a sectional view taken on the line 'Y Y.

2--2 of Fig. 1;

Figure 3 'is a fragmentary section on the linel 3-3 of Fig. 2.

In accordance with the invention Yas illustrated by way of example inthe drawing; use ismade of a household vessel, such as a pan I0,'of any'suitable depth adapted to contain water or other I2. The cover or hoodI I has steam outlet means in the form of an upstanding projectingtubular taperedv ymember or nozzle I3 centrally thereof and incommunication with the chamber I2. The

Ycover or hood on the lower edge portion thereof has a rolled rim I4which rests in contact with the pan. 'I'he cover or hood II is somewhatsmaller in diameter than the diameter ofthe pan I0, to provide asurrounding space designated I5. The top of the cover or hood I I-Wheren it joins the nozzle I3 is crinkled or'corrugated, as at I6. Thesecrinkles or corrugations are disposedradially `with respect tothevertical axis of the nozzle I3, to provide meanslraised from" thegeneral surface of the top of the cover or hood on which an article tobe sterilized may rest. In Fig. l there is shown a canning jar J restingon these corrugations the jar will be elevated and the spaces betweenthe corrugations I6 will provide passages II for the water ofcondensation which'may run back into the pan on the outside surface ofthe cover orV hood I I, and the passages II will also allow steam'VPATENT-f oFFlcl-: N

VThe lower edge of'` y to escape from the jar. after leaving the upper Yend ofv the nozzle I3 inthe. sterilizing action;

From the foregoing it will be obvious ,that there has been describedelementsv which may be com-,-

bined to practice a simple method for sterilizing varticles of thecharacter mentioned in the home.

In this connection it is'to be understood that the Ypan will contain asuitable quantity ofwater,y after which the accessory Amay be arrangediny the` pan I0. may be arranged on a suitable heater or stove'to heatthe water for the purpose of producing Wl5 TheV pan and associatedaccessoryA steam. When steam issues from the nozzle I 3, x Y

the articles to be cleaned or sterilized, one at a time may be arrangedover the nozzle I3'so as p pan space I5 will clean theV exterior surfaceIn this manner the jarwill be thorthereof. oughly sterilized.

I claim: In combination, an

open-topped water con-I tainer having a circular bottom and a Wallex,-AV rtending upwardly from the lcircumference of said bottom, a hoodof sheet material having a v smooth rim of substantially the samediameter asrsaid bottomY and adapted to engage the inside of thecontainer adjacent said circumference of the bottom, said hood falsohaving a .wall extending upwardly for a substantial distance from Vsaidrim and diverging from said container wall when the rim is so engagedVwith the container, a horizontal portion integral with said hood Wallandforming the top of the hoodsaid hood wall being imperforate for asubstantial distance 4downwardly from saidtop, a single nozzle disposedcentrally of said `top and extending up-Y wardly therefrom andcommunicating "with an opening in said top, said top extending outward-1y from said nozzle a substantial distance to form a support for theneck of a jar placed over said zle having a plurality of deformed partsforming surfaces of the top, the projections on said upper surface beingso located as to engage and support said jar neck and the recessesonsaid lower sur?r face communicating with said nozzle. f
